The Building Process

Dome Lift: Triodetic Domes can be assembled in many different ways. They can be erected while supported by crane as the dome is rotated (Smaller Domes 50’-100’). This option allows for fast assembly as the material is kept in one area. Once the section is installed, the dome is lifted for the next section to be installed.

Triodetic vaulted arches and domes have been used as treatment tank roofs and stockpile enclosures for many years. More recently geometry of application has allowed economical stockpile covers in very large spans exceeding 135 meters for use in both new and retrofit applications.

Dust emissions were problematic for our client (Teck Resources) when it was not possible to spray the ore on the conveyor belts with water to reduce dust.

To minimize dust emission, Triodetic was contacted to design and fabricate three 100 m diameter by 35 m high Geodesic Dome structures to cover each of the three stockpiles. The domes were designed with intent that the stockpiles would remain operational during the entire construction period.  Triodetic designed the domes using a tubular Triodetic frame structure in galvanized steel and a galvanized steel cladding system. Each dome has a basic diameter of 325 feet, and an overall surface area of 114,375 square feet.

Dome cladding is a curved corrugated galvanized steel deck with custom formed galvanized steel infill panels.

The maple leaf on the centre dome is made of 864 metal sheets and is bigger than a football field. It is 100 metres wide and 80 metres high.
